N.E.SAMSEL DART Filed July 17, 1926 [rob/c Samsc/ 11d hall PATENT OFFICE.
NOBLE E. SAMSEL, GF OAKLAND, CALIFORNIA.
Application filed. July 17,
further object is to provide a dart to v by hand and which will stick to object against which it strikes.
still further object is to provide a sucion cup on the end of a dart whereby a acuum may be caused which will hold the it in the position in which it strikes a lane surface, and which will release when the vacuum is broken.
. These objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout the sevviews and as described in the specification forming a part of this application and pointed out in the appended claims.
in the drawings of which I have shown the Figure 2 is a longisection on line 22 of Figure 3. rare 3 is a top plan view of the dart; and Figure l is a section of the central tube through the dart showing the release valve spring therein, all of which is slightly larger than the other views and has a central portion cut away.
in drawings 1 have shown the ball or body oi? my dart as A, which consists of a rubber hall about the size of a baseball. On one side thereof, I provide a rubber vacuum cup B of slightly smaller diameter than the hall and on the diametrically opposite side I provide a tail piece 0, which ered to the outer end thereof. [it the end or" said tail piece O I provide a tapered wing piece D made of three radially disposed fins, each projecting from the tail piece C at an equal angle from the other, cividing the space around the tail into three equal parts. The edge of the said vacuum cup is tapered to form a better gripping edge thereon. Centrally through the said rubber dart I provide a metal tube E which one end outwardly flanged and enlarged concave-convex dish thereon. he convex face of said dish is shaped to 1926. Serial no..12a,079.
'? conform with the concave side of the vacuum cup B, and a rubber covering 1 isprovided on the concave side of the disk F with its peripheral ed' e scaled. to or integral with the cup 13. The said disk F and the tube E are centrally bored, as at 2, to allow passage of air therethrough. In the upper end of said tube E, I provide a cross rod 3 to which I secure a spring 4:- The other end of said spring 4 is secured to a cap 5 by the eye bolt 6. The said cap 5 is made of metal and its lower edges, which rest against the said tube E, are covered with rubber so that when the cap 5 is held against the end of the said tube E no air can leak in or out through the said hole 2. The. said cap 5 acts as a valve for the tube E and the vacuum cup B, and after the dart has been thrown against a smooth surfaced single planed object it will be held there by the'vacuum action or the cup B. Thevalve or cap 5 will prevent air from entering the vacuum cup B through the tube E and provides a convenient means for releasing the suction therein. When the thrower desires to release the suction or vacuum he may pull the cap 5 out of the tube E and the air will enter the hole 2 and will release the vacuum in the cup B, 7 When the operator throws the dart the tail piece (3 and wing D will hold the dart on its course and will direct it so that the vacuum cup B will strike the target object first and when said cup'strikes the object the air will be forced out of the vacuum cup through the tube E and the suction thus created will hold the dart to the objective until the thrower desires to release it. To release the dart the cap 5 is raised from the tube E and air will enter the tube through the hole 2 and will enter the concave side of the vacuum cup B and release the vacuum and the dart may be thrown again.
Having thus described my invention I desire to secure by Letters Patent and claim 1. In a dart the combination of a spherical body ortion; a tail portion having wings forme on the outer end thereof; a vacuum. cup formed on the opposite side of said body from said tail; a tube havin one end flanged and passed centrally througi said tail, body and vacuum cup; a spring secured in the end said tube and a valve to close the end of tube carried in said body, tail and Wing porsaid tube attached to said spring and held ions and opening to the. interior of said nozanally closed by mid spring. vacuum cup; and means to regulate the 2. game device, comprising a body porpassage of air through said tube.
tion; integral tail portion; spaced apart in testimony whereof I have affixcd my fins on the free end of said mil; vacuum signature.
cup integral with said body; a longitudinal NGBLE E. SAMSEL.
